Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for suspending and supporting a heavy object by being connected to a rope which can be moved up and down to a crane or the like.

[0002]

2. Description of the Related Art In order to attach an outer wall material such as a PC board to a building frame, a heavy object suspension device is connected to a wire which is lifted by a crane, and the heavy object suspension device suspends and supports the PC board. By raising and lowering the wire, the PC board is set at a predetermined attachment position, and in this state, the PC board is attached to the building frame.

[0003]

As the above-mentioned heavy object suspending device, a horizontal member provided with a plurality of hooks is generally used. With this device, a heavy object, particularly a PC board, is suspended at a plurality of positions. Since it can be hung and supported, it can be hung and supported in a stable state.

However, the above-mentioned conventional heavy load suspending device only suspends and supports a heavy load, and there is a limit to the movement of the wire to the building frame side.
When the board is attached to the building frame, it is necessary to move the wire to the side of the building body most, and the operator sticks out the body from the building body and pulls the PC board to the building body side for installation.
The work is troublesome and dangerous.

In particular, when the outer surface of the building body has irregularities in the indoor / outward direction, when the PC board is mounted in the concave portion below the convex portion, it is suspended so that the wire does not interfere with the convex portion. Therefore, the distance between the wire and the concave portion, that is, the distance between the suspended PC plate and the concave portion is increased by the protruding length of the convex portion, and the operator pulls the PC plate toward the building frame side. Is very troublesome.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a heavy object suspension support device which can solve the above-mentioned problems.

[0007]

Means for Solving the Problems A movable body is movably provided in one direction on a main body 3 which is suspended and connected to a wire of a crane, and a cylinder for moving the movable body and an electromagnetic valve for supplying pressure oil to the cylinder. Valve, hydraulic pump 16 and electric motor 1
5 and a battery 18 are provided in the main body 3, a switching control of this electromagnetic valve can be performed by remote operation, and a heavy object is suspended and supported by the movable body.

[0008]

[Operation] The main body 3 is suspended by the wire of the crane, and the heavy object is suspended and supported by the movable body provided on the main body 3. In this state, the movable body is moved by the cylinder without moving the wire. A heavy object can be moved horizontally along the main body 3, and its movable body can be moved by remote control.
When installing the PC board on the building frame, do not move the crane wire, and at the
Since the C board can be moved to the building body side, the PC board can be easily and safely attached to the building body without the operator on the building body protruding the body.
